vTO ALL WHOM IT MAY GONCERN:

Be it known that L J. H. McKNIGHT, of Oakwood, in the county of Oakland, and State of'Michigan, have invented a new'and useful Improvement in Gates; and I do hereby declare that the following is aV full, clear, and exact description thereof, which` will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

Figure 1 is a side view of my improved gate, parts being broken away to show the construction, and showing inred lines the position of the parts when the gate is partially opened.

Figure 2 is a top or plan view of the same.

Similar letters ofreference indicate ycorresponding parts.

My invention has for its object to furnish an improved gate, simple in construction, strong, and durable, and which may be conveniently operated to open or close it without its being. necessary to get out of the carringe for that purpose. i

And it consists in the construction and combination of the various parts of the. gute, as hereinafter more fully described.

A is the front gate-post, which is slotted vertically or made in two parts, the inner sides ofthe upper ends of said parts being bevelled 'off or inclined so as to insure the gat-e passing down into proper position as it e ldescend-s. i

I3 is the rear gate-post, which is also slotted or made in two parts, to and between -which the rear end ofl the gate is pivoted, Y

C is the gate, which has rive horizontal bars, c, to the central one of which the others are connected. 'Ihe central horizontal barA is made larger and stronger than the others; is pivoted to and between the parts ot' the rear post B, and to its projecting rear end is attachedv the 'weight-box D, in which is'placed a sufficient weight to balance the gate C, when raised to about an angle of forty-five degrees (45.) l

4' lhe forward ends ofthe longitudinal bars c1 are connected to each other by the two shot bars'c, the adjacent ends of which are pivoted to each other and to the end of the central horizontal bar, and to which the ends of the other horizontal bars are pivoted, as shown in iig. I,

The roerende of the upper horizontal bars c are pivoted to the short connecting-bar c3, the lower end of which is pivoted tothe centralhorizontal bar.'

The rear ends of the lower horizontal bars are pivoted directly tothe rear post'B.

e* is a diagonal connectingbnr, the ,lower end ofwhich is pivoted to the rear part ofthe bottom horizontal bar, and the upper end of which is pivoted to the forward part of thc top horizontal bar, as shown in iig. 1.

The effect of the diagonal bar c4 is, when the gate is raised,'to cause the horizontal bars el tofold in towards the centralhorizontal. bar, as shown in fig. 1, so that the said bars may be close to each other when raised into a vertical position. u I. A

' "lo the upper end of the rear gate-post B is attached a cross-bar,"E, to the ends of which are pivoted the levers F, as showen in figs.'1 and 2. e

G isa rope or chain, the upper end of which is connected to ends of the two levers F, from which it passes around the pulley H, pivoted to the outer 'end ofthe arm I, attached to the post B. l The other end ofthe rope or chain G is attached to the weight-box D, as shown in iig. 1. By this arrangement, when the gate is either opened or closed, it may be moved to the opposite position by giving a short,

quick downward movement to the outer end of either of the two levers F, so as to give to the weighted end of the gate a downward on upward impulse, whiehwill carry the gate past its balancing-point, allowing it to be carried the rest ofthe way by th action of gravity.

J is the catch, which is pivoted to the sideof the rear gate-post B, and theforward end of which is bent inward, so that 'its'inward end may catch upon the rear side o f the connecting-bar c3.

By allowing the .catch J tocatchnpon the forward side of the upper end of the connecting-bar ci, the gate C may be held partially suspended, to allow sma-ll stock to pass back and forth beneathit. i

The rear end of the catch J is bent inward intoa position parallel with or nearly parallel with its inwardlyprojecting forward end, as shown in figs. 1 and 2. AThe rear end ofthe catch J is weighted, and is connected with the inner ends of thc levcrs F, so that as the said levers F are operated to open the gate C,lthe first effect vmay he to raisethe catch J from the bara, allowing the said gate C to be opened.

As the levers F are released, the weighted end of ,the catch J brings it back into proper position to again catch upon the bar c3 when the gate C is lowered, and fasten said gate shut.. d

Havingthus described my invention, what I claim as new, and desire to secure by Letters Patent, is 1. The gate C, formed by the combination of the horizontal bars el, pivotcd Yconnecting-bars c2 and c3, pivoted diagonal bar c, and weight-box D, with cach other and withthe gate-post B, said gate C being,r constructed and operating substantially as herein shown and described.

2. The combination of thelevers F and cord or chain G with the weighted pivoted gate 0 substantially as herein shown and described, and for the purpose set forth.

3. The weighted catch J, in` combination with the gate C, post B, and levers F, substantially as herein shown and described, and for the purpose set forth. p

The above specification of my invention signed by me, this 27th day of June, 1868.
